Answer:

Step-by-step explanation:

A= 3.142 x r x l

r=6

l=13

total surface area = area of the curved section + area of the base

area of curved section = 6x13=78pi

aeea of base= 6x6=36pi

78+36=114pi = 358.1cm squared

Ax+3=23 if a=0 plz help
VladimirAG [237]

Answer:

x = \frac{23}{a}

Step-by-step explanation:

Given equation is,

ax + 3 = 23

To solve this equation for the value of x isolate the variable 'x' on the one side of the equation.

Step 1,

Subtract 3 from both the sides of the equation.

ax + 3 - 3 = 23 - 3

ax = 20

Step 2,

Divide the equation by a,

\frac{ax}{a}=\frac{23}{a}

x = \frac{23}{a}

Therefore, x = \frac{23}{a} will be the answer.

How do u write 1.2 as a fraction
Ivahew [28]
Split the number into its whole number component and decimal component.

for the decimal component, 0.2 is the same as 2/10

Find the GCF of both 2 and 10 and that would be 2

divide both the numerator and denominator by the GCF 

simplify and you get 1/5

Lastly combine the whole number component with the fraction and your answer would be 1 1/5.
